Solve the problem.
-Assume that the sales of a certain appliance dealer are approximated by a linear function. Suppose that sales were $3500 in 1982 and $74,000 in 1987. Let x = 0 represent 1982. Find the equation giving yearly sales S(x).
A) S(x) = 70,500x + 3500
B) S(x) = 14,100x + 74,000
C) S(x) = 70,500x + 74,000
D) S(x) = 14,100x + 3500

Quizplus · Accepted Answer

The slope of the line is calculated as (74000 - 3500) / (1987 - 1982) = 14,100. The equation of the line is S(x) = 14,100x + 3500, where x = 0 represents 1982.
